Sohstt.exe

I keep getting this on my Google chrome download bar that it is starting to download whenever I click on something new on the forums. Can someone help me? I have already had this happen 3 times 1 time it got past me the other 2 times I stopped it and also my security software alerts me that this is a threat can a moderator confirm that this is happening to anyone else? also how can I stop this.

DO NOT OPEN THIS PROGRAM! This is the 2nd time this has happened. It is a different form of a cyber attack. Instead of trying to crash a website the person tries to send out an .exe file for people to download and hack their computers. Whoever is doing this it is HIGHLY illegal and you will be caught and brought to justice..
